Z is not closed under standard division, as surely as N isn't closed under subtraction and R isn't closed under exponentiation. That is a mathematical fact, not one about any particular language. What you are saying is that Python 2's "/" is _not_ standard division (you want to talk about the principle of least surprise...), and is therefore _not_ a standard arithmetic operation. It's not Euclidean division, either, since it gives a negative remainder for negative divisors. -- https://mail.python.org/mailman/listinfo/python-list
